Design and test of high precision dynamic power supply

In order to meet the demand of high precision dynamic power supply for accelerator development. This paper analyzes the key points of design such as circuit structure and control method of a high-precision dynamic power supply, and gives a reasonable test scheme for measuring the current tracking precision which is the necessary index for dynamic power supply. Finally, an experimental platform was built to verify the proposed methods. The experimental results show that the design scheme and test method of the power supply mentioned in this paper are reliable and effective.
